ABSTRACT

 

The research is to investigate the mineral composition and study about some physical factors influencing on deteriorated problems of historic stone inscription created in the reign of King Chulalongkorn (Rama V) in 1892. The mineralogical compositions of the historical stone inscriptions represented by X-Ray diffractometer technique were calcite (CaCO3), actinolite (Ca2(Mg,Fe)5Si8O22(OH)2) and calcium silicate (CaSiO3). The results from experimental processes were carried out using spatial temporal analysis and 2 dimension image processing. The data analyses asserted that the physical factors as follows: (i) moisture from rain or dew, (ii) heat from sunlight exposure, (iii) wind and (iv) salt precipitation from sea aerosol were physical factors inducing the degradation of the historical stone inscriptions significantly. The deterioration degree of historical stone inscriptions had a direct variability correlation to thermal alternation. Besides, spatial analysis demonstrated that weathering degree of the stone inscription from sunlight also relied on positional arrangement of the stone inscriptions. Aforementioned techniques and the results can be not only contributed to historical stone inscriptions at Chudhadhuj Palace Museum but also applied to the other approaches for proper efficiency restoration and conservation.
